podrían interesar otras formas de aberturas de difusión 150. Other forms of diffusion openings 150 may be of interest.
Haciendo referencia a la figura 3, se pone de relieve que las aberturas de difusión son cada vez más grandes según nos vamos alejando del orificio de alimentación de los gases EGR 104 siguiendo la conducción de distribución de los gases EGR 105. Las ventajas que provee esta característica se detallarán en lo sucesivo. Referring to Figure 3, it is highlighted that the diffusion openings are getting larger as we move away from the feed hole of the EGR 104 gases following the distribution path of the EGR 105 gases. The advantages provided by this feature will be detailed hereafter.
Las aberturas de difusión 150 del canal de distribución 105 se establecen para difundir los gases recirculados EGR (G2) aguas abajo del intercambiador de calor 10, evitando así que los gases EGR (G2) circulen por el intercambiador 10 y sean enfriados con los gases calientes que han de enfriarse (G1). Los gases EGR (G2) son gases ensuciados y contienen abundantes sustancias con posibilidad de acumular incrustaciones en el intercambiador de calor 10, por lo que un escape aguas abajo permite evitar cualquier daño del intercambiador de calor 10. The diffusion openings 150 of the distribution channel 105 are established to diffuse the recirculated gases EGR (G2) downstream of the heat exchanger 10, thus preventing the EGR gases (G2) from circulating through the exchanger 10 and being cooled with the hot gases to be cooled (G1). The EGR (G2) gases are dirty gases and contain abundant substances with the possibility of accumulating scale in the heat exchanger 10, whereby an exhaust downstream allows to avoid any damage of the heat exchanger 10.
En la circulación de los gases EGR (G2) por el canal de distribución 105, estos pueden verse llevados a condensarse. Los condensados son corrosivos y acarrean una disminución de la vida útil del intercambiador de calor 10 en caso de acumulación en el intercambiador de calor 10. Para eliminar este inconveniente, en un modo de realización no representado, las aberturas de distribución 150 están sensiblemente inclinadas hacia abajo, de manera que los condensados sean arrastrados fuera de la conducción de distribución de los gases EGR 105 por efecto de la gravedad, protegiendo así la conducción de distribución 105 y, de manera más general, el intercambiador de calor 10 contra una corrosión por los condensados. In the circulation of the EGR (G2) gases through the distribution channel 105, these can be taken to condense. The condensates are corrosive and lead to a decrease in the life of the heat exchanger 10 in case of accumulation in the heat exchanger 10. To eliminate this inconvenience, in an embodiment not shown, the distribution openings 150 are substantially inclined towards below, so that the condensates are dragged out of the EGR gas distribution line 105 by gravity, thus protecting the distribution line 105 and, more generally, the heat exchanger 10 against corrosion by the condensed
Decimos que las aberturas de difusión 150 están inclinadas hacia abajo cuando se extienden en una dirección oblicua al eje de circulación del flujo de gases que ha de enfriarse (G1) por el intercambiador de calor 10 y orientada hacia la placa inferior del intercambiador de calor 10. We say that the diffusion openings 150 are inclined downwards when they extend in an oblique direction to the axis of circulation of the gas flow to be cooled (G1) by the heat exchanger 10 and oriented towards the lower plate of the heat exchanger 10 .
Haciendo referencia a la figura 6, que representa la carcasa superior 110 de un elemento de intercambio de calor 100 según un tercer modo de realización de la invención, el canal de distribución de los gases EGR 105 comprende aberturas de difusión 171, de forma oblonga, pasantes por la carcasa superior 110 en su espesor en correspondencia con el gofrado superior correspondiente a la semienvuelta del canal de distribución de los gases EGR 105. Cuando se cierra el elemento de intercambio de calor 100 ensamblando sus carcasas superior 110 (representada en la figura 6) e inferior 120, las aberturas pasantes de cada carcasa 110, 120 entran en coincidencia, es decir, se alinean según un eje ortogonal a la placa, extendiéndose según la altura del elemento de intercambio de calor 100, para determinar aberturas de difusión 150 pasantes por el canal de distribución de los gases EGR 105. Referring to Figure 6, which represents the upper housing 110 of a heat exchange element 100 according to a third embodiment of the invention, the EGR gas distribution channel 105 comprises diffusion openings 171, oblongly, through the upper housing 110 in its thickness in correspondence with the upper embossing corresponding to the half-turn of the EGR gas distribution channel 105. When the heat exchange element 100 is closed by assembling its upper housings 110 (shown in Figure 6 ) and bottom 120, the through openings of each housing 110, 120 coincide, that is, they are aligned along an axis orthogonal to the plate, extending according to the height of the heat exchange element 100, to determine diffusion openings 150 through through the EGR 105 gas distribution channel.
Tal configuración de las aberturas de difusión permite facilitar la aspiración de los gases EGR (G2) por efecto Venturi. En efecto, si se atiende a un elemento de intercambio de calor 100 dentro de un intercambiador de calor 10 en su funcionamiento, este está comprendido entre dos canales de conducción de un flujo de gases que ha de enfriarse (G1) que barren respectivamente las caras externas de las carcasas 110, 120 del elemento de intercambio de calor 100. La circulación de un flujo de gases que ha de enfriarse (G1) a uno y otro lado de las aberturas de difusión 171 lleva consigo una aspiración, por efecto Venturi, de los gases EGR (G2) circulantes por el canal de distribución de los gases EGR 105 del elemento de intercambio de calor 100. Such configuration of the diffusion openings facilitates the aspiration of the EGR (G2) gases by Venturi effect. In fact, if a heat exchange element 100 is treated within a heat exchanger 10 in operation, it is comprised between two conduction channels of a gas flow to be cooled (G1) that sweep the faces respectively external of the housings 110, 120 of the heat exchange element 100. The circulation of a gas flow to be cooled (G1) on either side of the diffusion openings 171 carries with it an aspiration, by Venturi effect, of the EGR (G2) gases circulating through the EGR gas distribution channel 105 of the heat exchange element 100.
En la figura 6, se representan aberturas de difusión 171 de forma oblonga. Sin embargo, es obvio que igualmente podrían interesar otras formas de aberturas para favorecer la aspiración por efecto Venturi. In Fig. 6, diffusion openings 171 are shown oblongly. However, it is obvious that other forms of openings could also be of interest to favor aspiration by Venturi effect.
Haciendo referencia a la figura 6, se pone de relieve que las aberturas de difusión son cada vez más grandes según nos vamos alejando, siguiendo la conducción de distribución de los gases EGR 105, del orificio de alimentación de los gases EGR 104. Las ventajas que provee esta característica se detallarán en lo sucesivo. Referring to Figure 6, it is highlighted that the diffusion openings are getting larger as we move away, following the distribution path of the EGR 105 gases, from the feed hole of the EGR 104 gases. The advantages that Provide this feature will be detailed hereinafter.
Haciendo referencia a la figura 5, que representa una carcasa superior 110 del elemento de intercambio de calor 100 según un cuarto modo de realización de la invención, el canal de distribución 105 (gofrado superior 115) está separado del canal 102 (gofrado inferior 112) de circulación del fluido caloportador por unos medios de ruptura de puente térmico 180 que permiten aislar térmicamente el canal de circulación del fluido caloportador 102, por el que circula un fluido a baja temperatura (F), del canal de distribución de gases EGR 105, por el que circulan gases a alta temperatura (G2). Referring to Figure 5, which represents an upper housing 110 of the heat exchange element 100 according to a fourth embodiment of the invention, the distribution channel 105 (upper embossing 115) is separated from the channel 102 (lower embossing 112) of circulating the heat transfer fluid by means of thermal bridge rupture means 180 which allow thermally isolating the circulation channel of the heat transfer fluid 102, through which a low temperature fluid (F) circulates, from the EGR 105 gas distribution channel, by the one that circulates gases at high temperature (G2).
Siempre haciendo referencia a la figura 5, los medios de ruptura de puente térmico 180 se materializan en forma de una línea de ruptura térmica configurada a partir de rendijas longitudinales 180 practicadas, para cada una de las carcasas 110, 120 del elemento de intercambio de calor 100, entre los gofrados 112, 115; 122, 126, respectivamente correspondientes a ambos canales de circulación 102 y de distribución 105. Merced a las rendijas de ruptura térmica 180, los canales de circulación 102 y de distribución 105 tan solo quedan sujetos entre sí, sobre cada carcasa 110, 120, mediante espigas de sujeción 181 que se encargan de una sujeción mecánica de los canales 102, 105 unos respecto a otros, pero limitan las transferencias de energía térmica. Always referring to Figure 5, the thermal bridge rupture means 180 materialize in the form of a thermal rupture line configured from longitudinal slits 180 made, for each of the housings 110, 120 of the heat exchange element 100, between embossing 112, 115; 122, 126, respectively corresponding to both circulation channels 102 and distribution 105. Thanks to the thermal rupture slots 180, the circulation channels 102 and distribution channels 105 are only subject to each other, on each housing 110, 120, by clamping pins 181 which are responsible for a mechanical clamping of the channels 102, 105 with respect to each other, but limit thermal energy transfers.
Tales medios de ruptura térmica 180 permiten limitar, e incluso suprimir, la condensación de los gases EGR (G2) dentro de la conducción de distribución 105, protegiendo así de manera eficaz el elemento de intercambio de calor 100 contra la corrosión de los condensados. Such thermal rupture means 180 allow to limit, and even suppress, the condensation of the EGR gases (G2) within the distribution line 105, thus effectively protecting the heat exchange element 100 against the corrosion of the condensates.

En el transcurso del funcionamiento del motor de combustión térmico, en los cilindros del motor sobrevienen explosiones que generan ondas acústicas que se propagan por el motor y, particularmente, en sentido de aguas abajo a aguas arriba en la línea de admisión de gases. During the operation of the thermal combustion engine, explosions occur in the engine cylinders that generate acoustic waves that propagate through the engine and, particularly, from downstream to upstream in the gas intake line.
Las ondas acústicas en la línea de admisión de gases llevan consigo variaciones en la presión de los gases circulantes por el intercambiador de calor 10. En funcionamiento normal, la presión de los gases EGR (G2) circulantes en el interior de los canales de distribución 105 de los elementos de intercambio 100 es superior a la presión de los gases que han de enfriarse (G1) circulantes en el exterior de los elementos de intercambio 100, difundiéndose entonces los gases EGR (G2) con presión excesiva fuera del elemento de intercambio de calor 100 por las aberturas de difusión 150. Por las ondas acústicas y por las variaciones de presión que acarrean estas, la presión de los gases EGR (G2) circulantes en el interior de los canales de distribución 105 de los elementos de intercambio 100 es inferior en ocasiones a la presión de los gases que han de enfriarse (G1) circulantes en el exterior de los elementos de intercambio 100, teniendo entonces tendencia los gases que han de enfriarse (G1) con presión excesiva a precipitarse dentro del elemento de intercambio de calor 100, a través de las aberturas de difusión 105, y a ser arrastrados con los gases EGR (G2) en el canal de distribución 105 del elemento de intercambio de calor 100. The acoustic waves in the gas inlet line carry variations in the pressure of the circulating gases through the heat exchanger 10. In normal operation, the pressure of the circulating EGR (G2) gases inside the distribution channels 105 of the exchange elements 100 is greater than the pressure of the gases to be cooled (G1) circulating outside the exchange elements 100, then the EGR gases (G2) diffusing with excessive pressure outside the heat exchange element 100 through the diffusion openings 150. Due to the acoustic waves and the variations in pressure that they cause, the pressure of the circulating EGR (G2) gases inside the distribution channels 105 of the exchange elements 100 is lower in occasions at the pressure of the gases to be cooled (G1) circulating outside the exchange elements 100, then the gases that have to enf riating (G1) with excessive pressure to precipitate within the heat exchange element 100, through diffusion openings 105, and to be carried with the EGR gases (G2) into the distribution channel 105 of the heat exchange element 100 .
De este modo, según los gases EGR (G2) se van desplazando por el canal de distribución 105 del elemento de intercambio de calor 100, a los gases EGR (G2) se agregan gases que han de enfriarse (G1) penetrando en la conducción de distribución 105. Thus, according to the EGR gases (G2) they move along the distribution channel 105 of the heat exchange element 100, to the EGR gases (G2) gases to be cooled (G1) are added penetrating the conduction of distribution 105.
Los gases EGR (G2) se desplazan a lo largo del elemento de intercambio de calor 100. Se definirá, por convención, que los gases EGR (G2) se desplazan de izquierda a derecha, por el canal de distribución 105, con referencia a los lados izquierdo y derecho del canal de distribución 105 representados en la figura 4. The EGR (G2) gases travel along the heat exchange element 100. It will be defined, by convention, that the EGR (G2) gases travel from left to right, through the distribution channel 105, with reference to the left and right sides of the distribution channel 105 shown in Figure 4.
Según se van desplazando los gases EGR (G2) por el canal de distribución 105 de izquierda a derecha, los gases EGR (G2) se diluyen en el canal de distribución 105, lo cual disminuye su concentración, por lo que los gases EGR (G2) están menos concentrados en la parte derecha del canal de distribución 105 que en la parte izquierda. En otras palabras, los gases EGR (G2) quedan mal repartidos aguas abajo del intercambiador, estando los gases EGR más concentrados en la parte izquierda del intercambiador de calor. As the EGR (G2) gases move along the distribution channel 105 from left to right, the EGR gases (G2) are diluted in the distribution channel 105, which decreases their concentration, so the EGR gases (G2 ) are less concentrated on the right side of the distribution channel 105 than on the left side. In other words, the EGR (G2) gases are poorly distributed downstream of the exchanger, with the EGR gases being more concentrated on the left side of the heat exchanger.
Con objeto de eliminar este inconveniente, haciendo referencia a las figuras 3, 5 y 6, cuanto más alejadas del orificio de introducción de los gases EGR 104 se hallen las aberturas de difusión 150, más grandes serán las aberturas de difusión 150. En otras palabras, las aberturas de difusión 150 son más grandes en la parte derecha del canal de distribución 105 que las de la parte izquierda. Dicho de otro modo aún, cuanto menor sea la concentración de los gases EGR (G2) en el flujo de gases circulante por una zona del canal de distribución 105, mayor será la dimensión de la abertura de difusión 150 en la zona del canal de distribución 105. La dimensión de las aberturas de difusión 150 se establece para cubrir un caudal constante de gases EGR (G2) a lo largo del canal de distribución 105 para cada una de las aberturas de difusión 105, correspondiendo el caudal, en sentido matemático, al producto de la concentración de los gases EGR (G2) en el flujo de gases circulante por una zona del canal de distribución 105 por la dimensión de la abertura de difusión 150 practicada en dicha zona del canal de distribución 105. In order to eliminate this inconvenience, referring to Figures 3, 5 and 6, the farther the diffusion openings 150 are located, the larger the diffusion openings 150 will be. In other words , the diffusion openings 150 are larger in the right part of the distribution channel 105 than those in the left part. In other words, the lower the concentration of the EGR (G2) gases in the flow of circulating gases through an area of the distribution channel 105, the greater the dimension of the diffusion opening 150 in the area of the distribution channel 105. The size of the diffusion openings 150 is set to cover a constant flow of EGR gases (G2) along the distribution channel 105 for each of the diffusion openings 105, the flow corresponding, in a mathematical sense, to the product of the concentration of the EGR gases (G2) in the flow of gases circulating through an area of the distribution channel 105 by the dimension of the diffusion opening 150 practiced in said area of the distribution channel 105.
En virtud de la configuración de las aberturas de difusión 150 a lo largo del canal de distribución 105 de cada uno de los elementos de intercambio 100, los gases EGR (G2) se mezclan homogéneamente con el flujo de gases que ha de enfriarse (G1), y ello, pese a la presencia de ondas acústicas que llevan consigo variaciones de presión en el intercambiador de calor 10. By virtue of the configuration of the diffusion openings 150 along the distribution channel 105 of each of the exchange elements 100, the EGR gases (G2) are homogeneously mixed with the gas flow to be cooled (G1) , and this, despite the presence of acoustic waves that carry pressure variations in the heat exchanger 10.
Tras haber descrito la estructura de los medios de la invención, ahora se abordará su funcionamiento y su puesta en práctica. Having described the structure of the means of the invention, its operation and implementation will now be addressed.
Puesta en práctica de la invención Implementation of the invention
En el funcionamiento del intercambiador de placas 10, un flujo de gases de admisión (G1), destinado a ser consumido en un motor térmico de combustión, circula, de aguas arriba a aguas abajo, dentro del intercambiador de calor 10, por unos canales de conducción de un flujo de gases que ha de enfriarse conformados entre los elementos de refrigeración 100 del intercambiador de calor 10. In the operation of the plate exchanger 10, a flow of intake gases (G1), intended to be consumed in a thermal combustion engine, circulates, from upstream to downstream, within the heat exchanger 10, through channels of conduction of a gas flow to be cooled formed between the cooling elements 100 of the heat exchanger 10.
Por los canales de circulación de fluido caloportador 102 de cada uno de los elementos de refrigeración 100 del intercambiador de calor 10, circula un fluido caloportador (F) que intercambia calorías con el flujo de gases de admisión (G1) circulante por los canales de conducción de fluido. En los canales de distribución de gases EGR 105 de cada uno de los elementos de refrigeración 100 del intercambiador de calor 10, se introduce un flujo de gases EGR (G2). El flujo de gases EGR (G2) se difunde fuera de los elementos 100 por unas aberturas de difusión 150 practicadas en los canales de distribución de gases EGR 105. A heat transfer fluid (F) that exchanges calories with the flow of intake gases (G1) circulating through the conduction channels circulates through the heat transfer fluid circulation channels 102 of each of the cooling elements 100 of the heat exchanger 10 of fluid An EGR gas flow (G2) is introduced into the EGR gas distribution channels 105 of each of the cooling elements 100 of the heat exchanger 10. The EGR gas flow (G2) is diffused out of the elements 100 through diffusion openings 150 made in the EGR 105 gas distribution channels.
El flujo de gases EGR (G2) es enfriado, en este ejemplo, antes de ser introducido en los canales de distribución de los gases EGR. The EGR gas flow (G2) is cooled, in this example, before being introduced into the EGR gas distribution channels.
